Abstract
Способ определения средней скорости потока, перемещаемого по трубопроводу, при котором вводят в поток электромагнитные колебания фиксированной частоты и выводят из потока сигнал с доплеровской частотой, отличающийся тем, что создают базу данных доплеровских частот, формируют из этой базы данных набор частот, близких к средней доплеровской частоте, используют этот набор частот для вычисления арифметического среднего значения доплеровской частоты, и по этому значению частоты судят о средней скорости потока. A method for determining the average velocity of a stream moving through a pipeline, at which electromagnetic oscillations of a fixed frequency are introduced into the stream and a signal with a Doppler frequency is extracted from the stream, characterized in that they create a database of Doppler frequencies, form a set of frequencies close to the average Doppler frequency from this database frequency, use this set of frequencies to calculate the arithmetic average of the Doppler frequency, and the average flow rate is judged by this frequency value.
